    "Coding skills are an incredibly useful capacity for doing data analytics. In our first workshop, we covered the basics of the Python programming language:\n",

    " - expressions\n",
    " - statements\n",

    " - for loops\n",

    "The questions listed below are designed to stretch your coding skills *beyond* what is required for the vast majority of projects in the Corndel Data Analytics Diploma.\n",
    "\n",
    "By the end of this unit, we want every learner to be able to be;\n",
    " - comfortable manipulating different variables and data types\n",
    " - starting to develop the ability to *think algorithmically*\n",
    " - able to interpret basic if-else statements and for loops within existing code\n",
    "\n",
    "To complete the skills development task for workshop 3, you will need to answer 3 of the questions listed below. We have grouped them in order of difficulty. It is completely your choice which questions you answer."
